2020-11-13vyos.template: provide general is_ip(v4|v6) helpersChristian Poessinger
We had two places were the is_ip, is_ipv4 and is_ipv6 helpers had been defined. All places now have been converged into vyos.template as they are used both in the Jinja2 templates and also in our scripts.

2020-07-12snmp: T2687: replace 3rd party hash library with custom codeChristian Poessinger
The 3rd party library used for calculating the SNMP hashes in advance only worked for SHA and nod for MD5 as SHA was hardcoded [1]. The code has been replaced by a class-less implementation providing only the required functionality. [1]: https://github.com/TheMysteriousX/SNMPv3-Hash-Generator/issues/2
2020-07-11snmp: T2687: precalculate snmpv3 encrypted keysChristian Poessinger
As of now when adding new credentials for any SNMPv3 user we submit the credential either plaintext or encrypted. A plaintext credential will be hashed by SNMPd in the background and then passed back into the CLI so it's not stored in cleartext. This feels like the wrong way in changing the CLI content with data produced by a 3rd party daemon which implements the service. It feels like the tail wiggles the entire dog. This should be changed in the following way: - After retrieving the plaintext password from CLI, use Python to hash the key in advance - Re-populate the encrypted key into the CLI and drop the plaintext one - Generate service configuration and continue startup of SNMPd This also fixes a race condition when SNMPd started up but not properly provided the hasehd keys in the configuration resulting in a ConfigurationError. Now as we also support binding SNMPd to a VRF this fixes a deadlock situation on bootup as we can only bind late to the VRF and require up to 5 restarts of the service - but the service will never start.
2020-07-04snmp: vrf: T2682: support restart on failure indefinitely.Christian Poessinger
Linux tries to bind sshd to the VRF but it is yet not ready - for any arbitrary reason. After restarting SSH to often (rate-limiting) it is blocked by systemd. Using Restart/RestartSec is not enough - systemd services use start rate limiting (enabled by default). If service is started more than StartLimitBurst times in StartLimitIntervalSec seconds is it not permitted to start any more. Parameters are inherited from DefaultStartLimitIntervalSec (default 10s) and DefaultStartLimitBurst (default 5).
2020-06-16snmp: T2321: use restart of start in systemctlChristian Poessinger
For an unknown reason snmpd not always starts after reboot.

2020-05-29airbag: T2088: explicit enabling of the featureThomas Mangin
airbag must now be explicitly installed. the patch also allow to fully disables the installation of the logging code at setup (and not just installing and doing nothing)
2020-04-15dns-forwarding: T2298: fix path to control fileChristian Poessinger
After migrating PowerDNS to systemd and also its configuration files to a volatile directory in commit 77d725f ("dns-forwarding: T2185: move configuration files to volatile /run directory") the path for the control file has not been altered and pushed to the client rec_control binary"
2020-04-12template: T2230: use render to generate templatesThomas Mangin
convert all call to jinja to use template.render
2020-04-09util: T2226: os.system was wrongly converted to runThomas Mangin
os.system does print the ouput of the command, run() does not. A new function called call() does the printing and return the error code.
2020-04-06util: T2226: covert most calls from os.system to utilThomas Mangin
As little change a possible but the function call The behaviour should be totally unchanged.

2020-02-15snmp: T2042: stricter validation when deleting SNMP in combination with LLDPChristian Poessinger
A consistency check was missing to prevent deleting the SNMP configuration but still setting "service lldp snmp enable".
2020-02-09snmp: T1931: instead of searching a pseudo marker find real marker in configChristian Poessinger
As we need to operate with usmUser, we can search for it directly if its present or not. There is always one usmUser entry for the system user.

2019-10-27snmp: T1769: remove TSM (Transport Security Mode) supportChristian Poessinger
The SNMPv3 TSM is very complex and I know 0 users of it. Also this is untested and I know no way how it could be tested. Instead of carrying on dead and unused code we should favour a drop of it using a proper config migration script.
2019-10-27snmp: T818: T1738: remove per user/trap engine idChristian Poessinger
As of the SNMP specification an SNMP engine ID should be unique per device. To not make it more complicated for users - only use the global SNMP engine ID.

2019-01-30T1160: fix (ro|rw)community ACLChristian Poessinger
WHen building up the SNMP v2 community ro/rw access all hosts from a INET version could access even when the community was locked to one INET family. Example #1: set service snmp community bar network 172.16.0.0/12 Allowed access only to IPv4 network 172.16.0.0/12 but it allowed acces from IPv6 ::/0. Example #2: set service snmp community baz network 2001:db8::/64 Limited IPv6 access to 2001:db8::/64 but IPv4 was open to 0.0.0.0/0
